Investigation into the placement and connection of permanent survey marks for cadastral surveys

Abstract

This project investigates the recent trends in the placement of permanent survey
marks in Queensland, and reviews suitable methods of connecting cadastral surveys
to these marks. Many organisations utilising land information now require more
accurate spatial data for their operation. This necessitates the cadastre being
accurately connected to the geodetic mapping system which means coordination of
land boundaries.
To achieve the above aim an overall review of the existing Survey Control Database
(SCDB) has been made, both in the field and related to the various directions given to
Surveyors. The survey control infrastructure of two areas in South East Queensland
has also been analysed. The methods employed in the past for connection of surveys
will be analysed to develop the most suitable and cost effective method for today.
The initial results show that to provide suitable and efficient connections between the
survey control and land boundaries, there must be appropriate regulations and shared
responsibility between surveyors and Local Authorities. A major consideration in
applying new regulations is the cost and the expected timeframe for results to take
effect.
